IMPROVEMENT IN BED-BOTTOMS.

Specification forming part of Letters Patent No. 174,062, dated February 29, 1876; application filed July 26, 1875.

To all whom it may concern:

Be it known that I, EGBERT P. CARTER, of Arcade, in the county of Wyoming and State of New York, have made certain Improvements in Spring BcdBottoms, of which the following is a specification:

This invention relates to certain improvements in bed-bottoms; and consists of a novel construction and combination of parts, which will be fully hereinafter described, and specifically pointed out in the claims.

In the drawings, Figure l is a plan, and Fig. 2 a side elevation, one of the side rails being removed.

A A represent the two end pieces of a bedbottom, which are of wood, and bolted at the corners at a a to side pieces B B. These form the outside frame of the spring bed'bottom, the top and bottom or end pieces being precisely alike. The upper edge of both end pieces is hollowed out at regular intervals, leaving supports or-flat-topped ridges b b b. On the top of these a double or endless wire, 0 c, is stretched and held down by clips. At one end this wire goes around a pin, d, and at the other around an eccentric pin, 01, so that it can be turned and a proper tension be kept up, if it should stretch or slacken. This wire thus arranged forms a double spring-support for the slat-hangers O O G. The back end of each of these is grooved at the top, and in it the back wire 1) sets. The under side of the hanger is also grooved, and in this the other wire b sets, and may be held in place by a cleat or other device. This hanger thus has a downward spring on the front wire, and an upward spring on the back wire, and no matter What pressure is brought to bear on it it will keep its place and position. -To each of these hangers O G is suspended a slat, D, by means of a link, 0, fastened to or swinging on upper part f always bent up.

sufficient to force down the end of the slat, as shown in Fig. 2, the hanger being grooved near the upper end to receive the link. The construction of the slat is very important and is peculiar: a single strip of wood, f, is first taken and bowed upward, and there kept in place by a shorter strip of thin iron or other sheet metal, 9, set

underneath it, the extreme ends being turned up over the ends of the wooden slat, and then fastened by a pin or otherwise. The lower part 9 always remainsstraight, and keeps the This makes a double spring of the slat, the bow of the wood, and the spring of the metal, it the weight is the wooden part onto the metal strip. If not, the lower or metal strip acts as a holder of, and support to, the wooden strip.

By this arrangement of parts a spring is obtained from the wires b b,'the hangers O O,"

and the double slat D f 9, giving a strong and out.

I claim 1. In combination with the slats D D, the hangers O 0, arranged in connection with the double wire-supports I) b, as and for the purpose specified. 1

2. The wire-spring hanger-supports b 1), arranged in connection with the-end pieces of the frame A A and hangers O O, substantially as and for the purpose specified.

3. The eccentric posts d, in combination with the wire I) b, as and for the purpose hereinbefore explained.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
